Flame King 2-Stage Auto Changeover Propane Gas RV Regulator Kit with 2 12" Pigtails

The Auto-Changeover LP Regulator allows you to hook up 2 Propane tanks and the regulator automatically switches over to the second tank once the first one runs out (and vice versa). The indicator changes color to let you know when a tank has been depleted and needs to be refilled. The inlet is a 1/4" SAE inverted flare and the outlet is a 3/8" NPT female. Also included are 2 of the 12" pigtails to connect the regulator to the propane tank or propane supply.
